You know, there might be an easier way but the first thing that pops to mind is:
Declare @SumVal int;
Select @SumVal=Sum(Amount) From Expense;
Print @SumVal;
You can, of course, print any number of fields from the table in this way. Of course, if you want to print all of the results from a query that returns multiple rows, you'd just direct your output appropriately (e.g. to Text).
